' FLOWER PLANTER Box Filed may fr, 195s 5 INVENTOR Y W//am 7.' Reyno/d6' 'FLOWER PLANTER BOX Application May 7, 1956, serial No. 583,174 `s, claims. (c1. zzo-4) This invention relates to improvements in ower planter box. The principal objects of this invention are:

First, to provide a planter box construction that is easy to assemble yet rigid and water tight.

Second, to provide end construction for a planter box that permits quick and tight connection of a rectangular end wall to a U-shaped body so that the parts inter-brace each other and so that the joint will be water tight.

Other objects and advantages of the invention will be apparent from a consideration of the following description and claims. The drawings, of which there is one sheet, illustrate a highly practical form of the invention.

Fig. l is a side elevational view of a planter box embodying the invention.

Fig. 2 is an enlarged transverse cross sectional view taken along the plane of the line 2 2 in Fig. l.

Fig. 3 is an enlarged fragmentary longitudinal cross sectional view taken along the plane of the line 3-3 in Fig. 2.

The planter box consists of an elongated body panel 1 of U-shaped cross section with inturned stiening flanges 2 on its upper edges. End walls 3 having integral laterally turned flanges 4 on all edges are fitted telescopically over the ends of the body. The body panel is thin sheet metal and may have a wide variety of decorative colors, finishes or surface conligurations. The end walls 3 are also of thin sheet metal and may have harmonizing or contrasting finishes with reference to the body. Legs 5 may be secured to the bottom of the body by screws 6 passed through holes in the bottom of the body.

In order to make a rigid watertight connection between the body and the end walls, rectangular inner end walls 7 are pressed into the ends of the body from the inside. The inner walls 7 have integral, laterally inwardly turned flanges 8 on their sides and bottom that engage the inner side of the sides and bottom of the body 1 and hold ends of the body snugly against the flanges 4 of the end walls. The upper edges of the inner walls project upwardly as at 9 and abut against the upper flanges on the outer end walls.

The inner walls are permanently held in place and the joints are made water tight by a layer or film of adhesive 10 located between the inner walls 7 and outer walls 3. The adhesive is applied to one of the walls and flows over all the opposed surfaces and into the cracks of the joint when the inner and outer walls are pressed together. The adhesive is characterized as being water insoluble and capable of forming a strong bond to metal surfaces. An

adhesive having the formula IEC-1099 sold by the Minne- Sota Mining and Manufacturing Co. is highly satisfactory for the purpose. It is a light tan material having a thin syrup consistency and consists of a synthetic rubber base dissolved in acetone. It has about 32% by weight of solids and weighs about 7.4 pounds per gallon.

Having thus described the invention, what is claimed as new and is desired to be secured by Letters Patent is:
